Rhinebeck is getting its own stimulus package, this week: Chelsea Clinton’s wedding on Saturday to Marc Mezvinsky—touted as the “event of the year” with a superstar-studded guest list of 500—will cost between $3 million and $5 million, the New York Daily News reports. At $3 million, the Clinton-Mezvinsky vows will cost $1 million more than the union of Tom Cruise and Katie Holmes. But Clinton’s is more important than any celebrity wedding, experts say, and could be a major influence on nuptial trends. The air-conditioned tents alone will cost $600,000 to keep guests cool on the private New York estate, and security to keep out gate crashers could run $200,000. One wedding planner estimates that the invitations alone could have cost more than $150 apiece.
